DIN standard chemical anchor bolt good quality stainless steel material cheap price

Chemical anchor bolts form a strong anchoring system by tightly bonding the screw and substrate through the solidification reaction of chemical agent tubes

Are chemical anchors suitable for cracked concrete?

Yes. High-quality chemical anchors are designed for both cracked and non-cracked concrete, providing reliable structural fastening.

How strong is a chemical anchor bolt? 

Curtain wall installation is mostly carried out at high altitude and exposed to outdoor environments for a long time. The chemical anchor bolts that meet the dual standards have good acid and alkali resistance, aging resistance, and water stain resistance. They have no creep at room temperature and can be used stably in the temperature range of -5 ℃ to 40 ℃ without frequent maintenance. This not only ensures the construction safety of curtain wall installation, but also extends the service life of curtain walls, and is suitable for the installation needs of various types of curtain walls such as glass curtain walls and stone curtain walls. In addition, the anti-corrosion requirements for anchor bolts in steel structure fixation are high, and hot-dip galvanizing, powder zinc infiltration or stainless steel materials are often used. The anti-corrosion standards are higher than those of the steel structure itself, which can effectively resist corrosion in outdoor, industrial pollution areas and other environments. Especially, anchor bolts made of 316 stainless steel can adapt to high salt spray environments such as coastal areas, ensuring the long-term stability of the anchoring system. At the same time, strict adherence to the use specifications of group anchors is required, and the mixing of different types and specifications of anchor bolts is prohibited to avoid safety hazards from the source. For the fixation of heavy-duty equipment, it is recommended to use 10.9 grade high-strength anchor bolts with high thixotropy adhesive, and strictly follow the installation process to ensure that drilling, hole cleaning, adhesive injection, curing and other processes meet the specifications. Incomplete hole cleaning may lead to a 50% decrease in anchor bolt bearing capacity, and burial depth deviation will also significantly affect the bearing performance, ensuring that the anchoring effect meets the standards.
